IMPROVEMENT IN FASTENERS FOR THE MEETING-RAILS OF SASHES.

Specification forming part of Letters Patent No. 180,877, dated August 8, 1876; application fi ed February 3, 1875.

To all whom it may concern:

, Be it known that I, J. STONE HEACOGK, of Buffalo, in the county of Erie and State of New York, have invented an Improvement in Window-Fasteners, of which the following is a specification:

The primary object of my invention is to prevent burglars from moving'the levers of window-fasteners by operating from Without with thin instruments thrust between the sash.

My invention consists of a spring secured directly to the rail of the sash, and provided with a rectangular notch, into which the leverarm automatically locks itself, as will be hereinafter more fully set forth and definitely claimed.

Figure 1 is a plan view embodying my invention. Fig. 2 is a side view of the same.

A is a piece of spring metal, or some other suitable substance, of sufficient length, breadth, and thickness to hold the lever securely against turning, in form resembling the handle of a spoon, having a notch, a, near the middle of the curve of width and depth sufficient to receive and hold immovable the end of the lever. O, B, and D are the fixed parts of an ordinary window-fastener. The spring for locking the lever O in the proper radial position is independent and separate from the segmental guide D, which, with the lever O, serves to draw the meeting-rails together. The spring A is also so shaped that the end of the lever may ride up to and into the slot at. It will also be observed that the spring A may be applied to and used with the ordinary fasteners now in use without any modification of said fasteners.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-- A single spring, secured directly to the rail of the sash, and provided with a rectangular slot, into which the lever-arm automatically locks itself against movement in either direction, substantially as described and shown, for the purpose set forth.
